IMPROVEMENT IN SNAP-HOOKS.

Specification forming part of Letters Patent No.'122,127,dated DecemberA26, 1871.

To all persons to whom these presents may c0me:

Be it known that I, LEWIS MORSE, of Attleborough, of the county ofBristol and State of Massachusetts, have invented an Improved Snap Hook;and do hereby declare the same to be fully described in the followingspecih'cation and represented in the accompanying drawings, of which-Figure l is a side view, and Fig. 2 a longitudinal section of suchsnap-hook. Fig. 3 is a representation of one-halfoi' the snap-hook,hanger, and body, as struck from a plate of metal by means of dies.

The common snap-hook, as ordinarily made, has its tongue constructedseparately from the body, and connected thereto by a hinge, and restingagainst a spring entirely separate from the hinge, the spring beingsolnetimes placed in the shank ot' the body and at other times withinthe bow or hook. One distinguishing feature ofdifference between mysnap-hook and others above referred to, asusually made, is that thetongue is connected to the body by the spring, which, by itsarrangement, answers the purposes of a hinge for the tongue, and aspring for closing it against the oblique end of the hook part of thebody. Another distinguishing feature is that the body and tongue areiirst struck together from two thin plates of metal, each partso struckhaving the torni shown in Fig. 3, wherein the hook and tongueparts arein the forni of a bow or yoke chan' neled throughout, and connected tothe shank, which is also channeled. Two of the said parts, shown in Fig.3, are laid and soldered together at their edges, after which the tonguepart is to be sawed or cut from the shank and hook portions, andreconnected with the shank by means of a short steel spring extendedinto both, and

soldered or fastened to them.

In the drawings, a denotes the hook; b, the tongue; c, the shank; d, thespring; and e the swivel eye, the. latter heilig iixed onthe journal rpoint of the shank. The spring d, by being entirely inclosed within thetongue and shank, is not only protected from injury and loss, but servesthe double purpose of a hinge and a spring.

I make no claim to any thing, combination, or arrangement of parts, asshown or described in the United States Patent No. 55,563, the springot' my improved snap-hook being arranged dii'- ferently, relatively, tothe tongue and body from Vanything represented in such patent.

hook as made with its tongue and body composed ot' two bows struck orformed from plate metal and soldered together, and the tongue next cutor separated from the body, and next reconnected therewith by a springarranged `in and xed to the two, as described, whereby the spring ismade to serve a double purpose, as explained.

Witnesses: LEWIS MORSE.
